    BackgroundHemichorea may point to a structural lesion in the contralateral basal ganglia with a large list of possible causes. Cavernous angioma may be rarely a possible cause for acute appearance of this movement disorder.Case DescriptionWe present a rare case of a 32-year-old female patient with hemichorea caused by a cavernoma (or cavernous angioma) in the contralateral insula and putamen with complete improvement of symptoms with surgical resection of the lesion.ConclusionsWe believe that surgical resection of basal ganglia cavernomas may be feasible with minor risks and resolution of clinical symptoms in the immediate postoperative period.Copyright © 2020 Elsevier Inc.
